Most of these "console ports" you speak of aren't really "ports." They're multiconsole. When the game comes out at the same time, it's multiconsole. When it comes out afterwards. It's a port. The Vita has some ports for sure, but most of what everyone is calling ports aren't ports at all.
Also where is all this shovelware you speak of? There's no shovelware when it comes to retail releases and I don't know anyone who would expect most digital games to be worth a damn.
